These are the conference proceedings of the 4th Haifa Veri?cation Conference held October
27-30 2008 in Haifa Israel. This international conference is a unique venue that brings
together leading researchers and practitioners of both formal and dynamic veri?cation for both
hardware and software systems. This year's conference extended the successes of the previous
years with a largejumpinthenumberofsubmitted papers. Wereceived49totalsubmissions with many
more high-quality papers than we had room to accept. Submissions came from 19 di?erent
countries re?ecting the growing international visibility of the conference. Of the 49
submissions 43 were regular papers 2 of which were later withdrawn and 6 were tool papers.
After a rigorous review process in which each paper received at least four independent reviews
from the dist- guished Program Committee we accepted 12 regular papers and 4 tools papers for
presentation at the conference and inclusion in this volume. These numbers give acceptance
rates of 29% for regular papers and 67% for tool papers (34% combined) - comparable to the
elite much older conferences in the ?eld. A Best Paper Award selected on the basis of the
reviews and scores from the Program Committee was presented to Edmund Clarke Alexandre Donz´
e and AxelLegayfortheirpaperentitledStatisticalModelCheckingofMixed-Analog Circuits with an
Application to a Third-Order Delta-Sigma Modulator. The refereed program was complemented by an
outstanding program of - vited talks panels and special sessions from prominent leaders in
the ?eld.
